Are there instructions somewhere on how to do this? Perhaps add a
README with details or a few links?

Can we use device tree for this board? I have just received one so if
you don't have the time for this I could give it a try (once I figure
out how to get U-Boot onto the board).
Also, do you know anything about the SDRAM controller? I don't see
mention of it in the docs and we would need it to create an SPL for
this board.
